A method of providing a function in a variable-function device. The method comprises providing a variable-function device, transmitting operative power from a function-producing device (e.g. a computer) to the variable-function device when the function-producing device is in an “off” mode, removing a function (e.g. a computer function) from the function-producing device, and providing the removed function in the variable-function device.

TECHNICAL FIELD

[0001] Embodiments of the present invention relate generally to computer systems. More particularly, embodiments of the present invention provide an energy efficient variable-function (and/or multi-function) apparatus and method.

BACKGROUND

[0002] Computers (such as personal computers, notebooks, laptops, palmtops, hand-held processing devices, and/or other types of computing devices) typically show notification items and other graphical items in an area of their display screen. Such notification items include, for example, electronic mail arrival notifications, instant messaging notifications, low battery-power warnings, and/or the like. These notifications can often interrupt the images or items being viewed by the computer user. As a result, these notifications can make the viewing experience of the user less pleasant, particularly if the user is viewing, for example, an entertainment-related image or program on the computer screen or if the user does not wish to be distracted while using the computer. The above-mentioned notification items may also clutter the display screen presentation of the computer, and/or may otherwise confuse or cause an inconvenience to the computer user, particularly if, for example, the computer screen has a small viewing surface area.

[0003] In addition, some computer users may place the computer underneath their desks or tables in order to increase the available surface area on their desks or tables. As a result, these computer users will not be able to view any notifications that may occur on the out-of-sight computer display screen or on a computer display screen that has been turned off (if there is a display on the PC itself).

[0004] In addition, functionalities in current computers continue to increase. As a result, the base systems of current computers are being burdened (and/or are becoming more complex and expensive) due to the increasing functionalities.

[0005] Current computers also integrate extra buttons, additional sensitive or fragile components, infrared (I/R) receivers, and/or other components into the computer bezel. The extra buttons and/or sensitive/fragile components typically result in higher support/service requirements and in increased costs of services for a computer device. Additionally, these additional components in the bezel may increase the manufacturing and design costs for a computer device.

[0006] For an I/R receiver integrated in the bezel, the I/R signal from the remote control device must be received in the line-of-sight of the I/R receiver. Thus, an I/R receiver integrated in or attached to the bezel will not be able to receive the I/R signals from a remote control device if, for example, the computer bezel is on the floor or is obstructed by an item on the user's desk.

[0007] Therefore, the above-described products typically are limited to particular capabilities and features and suffer from a number of constraints related to high cost, limited functionality, complexity in use, higher service/support requirement, increased manufacturing and design issues, inconvenience for the computer user, and/or other constraints.

SUMMARY

[0008] In accordance with an embodiment of the invention, an apparatus capable of interacting with another device includes: a module configured to provide a functionality, where the apparatus is configurable to support a second module for providing an additional functionality in order to permit variable functionality by the apparatus.

[0010] In another embodiment, a method of manufacturing a variable-function device includes: providing a module configured to provide a functionality, where the variable-function device is configurable to support a second module for providing an additional functionality.

[0011] In another embodiment, a method of providing functionality in a variable-function device includes: removing a functionality from a computer that can communicate with the variable-function device; and providing the removed functionality in the variable-function device.

[0012] Another embodiment of the present invention broadly provides a power source, a computer coupled to the power source and having a power switch for allowing operative power to be provided to the computer when in an “on” position and for terminating operative power to the computer when in an “off” position, and a variable function device (e.g. a device having a microprocessor) having a generally fixed circuitry and receiving operative power from the computer when the power switch is in the “off” position. The variable function assembly may also comprise a first module coupled to the generally fixed circuitry so the variable function device may provide a first function, and a second module coupled to the generally fixed circuitry so the variable function device may provide a second function. A video generating system (e.g. a television) may be coupled to the computer. An audio volume controller and at least one controller may be coupled to the variable function device for controlling the same. A clock (e.g. a real time clock) may operatively engage the variable function device. A VCD-controlled device, such as an encoder or any other suitable device that is capable of being controlled by the variable control device may be coupled to the variable control device.

[0013] A further embodiment of the present invention provides a method of providing a function in a variable-function device comprising providing a variable-function device, transmitting operative power from a function-producing device (e.g. a computer) to the variable-function device when the function-producing device is in an “off” mode, removing a function from the function-producing device, and providing the removed function in the variable-function device. The removed function may comprise a function selected from the group consisting of an input-function, an out-put function, an entertainment function, an information resource function, a security function, a system display function, a system control function, a telephony function, a communication function, a notification function, a productivity function, a transaction function, a value-added service function, a logical window function for a computer, an education function, at least one of audio and visual control function, a device control function, and an advanced functionality function. The method of providing a function additionally comprises connecting the function-producing device to the variable function device through a communication link (e.g. wired path or a wireless path). The variable-function device preferably comprises a module capable of permitting and providing removal of a function from the function-producing device.

[0014] In one embodiment the module has an input stage for receiving an input and an input interface coupled to the input stage for processing the received input. The input interface may comprise a matrix switch.

The method for producing a plurality of functions may further comprise replacing the first module with a second module coupled to the generally fixed circuitry in the variable function device, and generating a second function with the assistance of the second module and the generally fixed circuitry of the variable function device. The removed functions may be displayed. If the function-producing device comprises a computer the method may additionally comprise generating operative power from the computer to the variable function device, preferably when the computer is in an “off” mode, coupling a monitor to the computer and displaying one or more of the removed functions on the monitor. A signal may be sent from the variable function device to the function-producing device to place the function-producing device in an “on” position. The method for producing a plurality of functions also may further additionally comprise at least one of the following: coupling a clock to the fixed circuitry, sending a first signal from the clock, which is preferably a signal adjusted-clock, to produce operative power for the function-producing device, recording an entertainment function after sending the first signal from the clock, and adjusting the clock to send a second signal at a desired time to cause termination of the recording of the entertainment function which may be stored (e.g. in the memory of the computer, or the like) prior to recording the same.

[0017] A further embodiment of the present invention provides a variable function assembly comprising a power source, a computer means coupled to the power source and having a power switch for allowing operative power to be provided to the computer means when in an “on” position and for terminating operative power to the computer means when in an “off” position; and a means, coupled to the computer means, for producing a plurality of functions and including a generally fixed circuitry and receiving operative power from the computer means when the power switch is in the “off” position. The variable function assembly may comprise a first module coupled to the generally fixed circuitry so the means for producing a plurality of functions may provide a first function, and a second module coupled to the generally fixed circuitry so the means for producing a plurality of functions may provide a second function.

[0018] Another embodiment of the present invention provides a method of providing a function in a variable-function device comprising removing a first function from a functionality-providing device operatively communicating with a variable-function device and having a power switch for allowing operative power to be provided to the functionality-providing device when in an “on” position and for terminating operative power to the functionality-providing device when in an “off” position, and providing the removed first function in the variable-function device. Preferably, the removing of a function from the functionality-providing device comprises removing the function when the power switch of the functionality-providing device is in the “off” position. As indicated, the variable function device includes a generally fixed circuitry to which at least one module is coupled to assist in removal of any desired function. Any module may be replaced with another module to assist in removing and providing a different function in the variable-function device.

[0019] A further embodiment of the invention provides an article of manufacture comprising a machine-readable medium having stored thereon instructions for: removing a first function from a functionality-providing device operatively communicating with a variable-function device and having a power switch for allowing operative power to be provided to the functionality-providing device when in an “on” position and for terminating operative power to the functionality-providing device when in an “off” position; and providing the removed first function in the variable-function device.

[0020] Another embodiment of the invention provides a variable function assembly comprising a network, a module, a functionality-providing device coupled to the network, and a variable function device coupled to the network and having a generally fixed circuitry coupled to the module and employing a Universal Plug and Play (UPnP) standard to permit the module to generate output relating to a state change of the functionality-providing device. The module may control the functionality-providing device by use of the UPnP standard.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0046] In the description herein, numerous specific details are provided, such as examples of components and/or methods, to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that an embodiment of the invention can be practiced without one or more of the specific details, or with other apparatus, systems, methods, components, materials, parts, and/or the like. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of embodiments the invention.

[0047]FIG. 1 is a block diagram of a system 100 in accordance with an embodiment of the invention. The system 100 may include a computer 105, and a variable-function device 110 that can communicate with the computer 105 via communication path 115. It is understood that for purposes of explaining functionalities of embodiments of the invention, the elements in the drawings are not necessarily drawn to scale. As described below, the communication links shown in the drawings, such as, for example, the communication path 115 or the path of input 145, may be a wired connection, wireless connection, bus connection, network connection, and/or other types of suitable communication links.

[0048] The computer 105 may be, for example, a personal computer, notebook, laptop, palmtop, handheld processing device, and/or another type of computing device. However, as described in another embodiment below, the computer 105 may instead be another type of device, such as, for example, a printer or other peripheral devices.

[0049] Typically, the computer 105 includes an input/output (I/O) interface 120, a processor 125, and a display screen 130. For purposes of describing embodiments of the invention, other known elements in the computer 105 have been omitted in FIG. 1.

[0050] In one embodiment of the invention, the variable-function device 110 includes an I/O interface 135 and at least one module 140 for performing at least one particular function (or functionality) as described further below. As also described below in another embodiment, at least an additional module for performing a particular functionality may be added to (or integrated with) the variable-function device 100 in order to permit the variable-function device 110 to provide a variable number of functionalities. The I/O interfaces 120 and 135 are coupled by the communication link 115 so that communication (or interaction) can occur between the computer 105 and the variable-function device 110. The communication link 115 may be a wired or wireless communication path. For example, the communication link 115 may be a cable, a wire(s), a bus connection such as a universal serial bus (USB) or another type of bidirectional bus, and/or other suitable wired or wireless links.

[0051] USB is a serial bus for connecting peripherals to a computer, and was developed by Intel Corporation, Santa Clara, Calif. The USB external bus standard supports data transfer rates of, for example, approximately 480 Mbps (480 million bits per second), with possibilities of greater bandwidth in the future. A single USB port can be used to connect up to, for example, about 127 peripheral devices, such as mice, modems, and keyboards. USB also supports Plug-and-Play (PnP) installation, hot plugging, and multiple data streams.

[0052] Of course, the communication link 115 may also be a connection in a local area network (LAN), wide area network (WAN), or another type of network where the computer 105 and the variable-function device 110 can communicate with each other via paths in the network.

[0053] The communication link 115 may also be a wireless path where, for example, infrared (I/R) or radio frequency (RF) communication can occur between the computer 105 and the variable-function device 110. A suitable wireless protocol, such as, for example, the Bluetooth wireless protocol, the Digital Enhanced Cordless Telecommunications (DECT) technology, or the IEEE 802.11 standards, may be used in the wireless communication process between the computer 105 and the variable-function device 110.

[0054] The I/O interfaces 120 and 135 may be, for example, serial ports, parallel ports, universal serial bus (USB) ports or other bus ports, infrared interfaces, radio frequency (RF) interfaces, transceivers, receivers and transmitters, other wired communication interfaces, other wireless communication interfaces, and/or other suitable communication interfaces.

[0055] The interface types for the I/O interfaces 120 and 135 will typically depend on the type of communication link 115 between the computer 105 and the variable-function device 110, and/or on the constraints in the computer 105 and the variable-functional device 110.

[0056] In one embodiment the variable-function device 110 includes an input-function module 140 that can provide an input-related function (or input-related functionality). Examples of input related functions or functionalities are described in detail below. As also described below, the variable-function device 110 can also include, for example, an output-function module, a combination of at least one input-function module and at least one output-function module, multiple input-function modules, multiple output-function modules, a single input-function module and multiple output-function modules, a single output-function modules and multiple input-function modules, and/or multiple input-function and output-function modules.

[0057] The input-function module 140 can receive an input 145 from a user (or from another device). The input 145 may be processed (e.g., encoded or decoded) by the I/O interface 135 for transmission via communication link 115 as signal 145 a. The signal 145 a is then processed (e.g., decoded or encoded) by the I/O interface 120 in the computer 105. Based upon the signal 145 a (which is, in turn, based upon the input 145), the processor 125 in the computer 105 can permit or execute a desired function or feature, such as, for example, switching the computer 105 into an on-state, having the computer 105 send an e-mail in a network, or showing a content or program 150 on the computer screen 130. Thus, an input 145 (e.g., the user pressing one button or other user-actions) may be performed by the user via the variable-function device 110 to permit a desired operation or feature to be performed in the computer 105.

[0058] However, it is noted that an input 145 may not necessarily be transmitted via the link 115 to permit a desired event occurrence in the computer 105. For example, the input 145 may be transmitted to another device via another communication path. As another example, the input-function module 140 may be a memory device that can store data as provided by the input 145. This stored data may, for example, be subsequently read by the computer 105 or by any other suitable device that can communicate with the variable-function device 110. As also described below, in response to an input 145, the variable-function device 110 may provide an output function (or output functionality). For example, an input 145 may cause the variable-function device 110 to output a picture image, a photograph, an advertisement, a text message, lighting, music or other audio output, a logo such as an “HP” logo from HEWLETT-PACKARD COMPANY of Palo Alto, Calif., a video, and/or other output functionalities, as described in detail below.

[0059] Various known design schemes or methods for integrating a component in a device may be used to integrate or include an input-function module 140 in a variable-function device 110. An example of a suitable design scheme or method may be of the type used for manufacturing the product known as JORNADA from HEWLETT-PACKARD COMPANY.

[0060] As an example as shown in FIG. 2, the input-function module 140 in FIG. 1 may be a module 140 a to permit a user to change a mode in the computer 105. In this specific case, the module 140 a may include an input stage 200 that may be, for example, a mode switching button(s) or mode control element(s), a light-detector, a sound-detector (e.g., a microphone), and/or other suitable elements that can accept an input command. The module 140 a may further include an input interface 205 for transmitting or processing the input received by input stage 200. The input interface 205 may be, for example, a matrix switch (e.g., a 3-by-5 matrix switch).

[0061] As another example as shown in FIG. 3, an input-function module 140 b may include an input stage 300 that may be a receiver (or transceiver) and an amplifier stage 305 for amplifying to signals from the receiver. The receiver can receive a wireless input signal(s) 310 from a user via a device 315 such as, for example, a remote control device, microphone, network node, digital camera, infrared (I/R) blaster, another computer or processing device, and/or other types of devices. For example, the device 315 may be a node, in which case, the communication path defined by the input signal 310 is a network path. The input signal 310 is received by the receiver and amplified by the amplifier 305 and transmitted via communication link 115 to permit the computer 105 to perform desired functions. As another example, the device 315 may include a remote control device for sending inputs 310 or other commands to the variable-function device 110. As noted above, in some instances, an input (such as the input 310) to the variable-function device 110 is not necessarily transmitted via communication link 115 to the computer 105.

[0062] The device 315 may include, for example, an output interface 350 and a source 355 to permit the transmission of the signals 310 to the variable-function device 110. The interface 350 may include, for example, a transmitter (or transceiver) 360, a signal driver 365, and/or other suitable components to permit the transmission of the signals 130.

[0063] The input signal 310 may be, for example, infrared signals, RF signals, and/or other wireless commands or signals. The receiver 300 may also be configured to receive other frequencies of the electromagnetic spectrum such as, for example, Ultrahigh Frequency (UHF), Very High Frequency (VHF), microwave, and/or other frequencies. The input signals 310 may also be wire-transmitted signals if an optional wire or bus link 320 is implemented between the variable-function device 110 and the device 315.

[0064] As another example as shown in FIG. 4, the variable-function device 110 may be configured with multiple input modules 140 a and 140 b to permit multiple types of input-related functionalities. For example, the variable-function device 110 may be configured with multiple input modules to permit the variable-function device 110 to receive both manual user inputs 400 and wireless input commands 405 in order to permit the computer 105 to perform desired functions by use of the variable-function device 110. The number of input modules in the variable-function device 110 may vary. Thus, in one embodiment, the modules 140 a and 140 b can perform different input functionalities or/and similar input functionalities.

[0065] In one embodiment, a method of manufacturing the variable-function device 110 includes providing a module configured to provide a functionality. The variable-function device 110 is configurable to support a second module for providing an additional functionality. At least a second module can be included in or integrated with the variable-function device 110 in order expand the functionality of the device 110.

[0066] As shown in FIG. 5, if, for example, the input-function module 140 c includes a USB hub or another type of bus hub, then at least one device 500 (e.g., devices 500 a and 500 b) can be coupled to the input-function module 140 c. The devices 500 may be, for example, key boards, mice, and/or other peripheral devices, and/or other suitable devices.

[0067]FIG. 6 is a block diagram of a variable-function device 110 in accordance with another embodiment of the invention. The variable-function device 110 includes an output-function module 600 that can transmit an output 605 to a user (or to another device), where the output 605 may represent an output function (or output functionality) as described in detail below. A control signal (or control signal with data) 605 a from the computer 105 is typically transmitted via communication link 115 and is processed by I/O interface 135. The output 605 is then generated by the output-function module 600 based upon the signal 605 a from the computer 110. Examples of different types of outputs 605 from the output-function module 600 are described below.

[0068] As another example, an output 605 may be generated based on a signal provided by another device that can communicate with the variable-function device 110. One example of such another device is a device 1310 (FIG. 13) which can provide an input 1307 to permit an output-function module 600 to perform a particular output functionality.

[0069] Reference is again made to FIG. 6. Various known design schemes or methods for integrating a component in a device may be used to integrate or include an output-function module 600 in a variable-function device 110. An example of a suitable design scheme or method may be of the type used for manufacturing the product known as JORNADA from HEWLETT-PACKARD COMPANY.

[0070] As an example as shown in FIG. 7, the output-function module may be a module 600 a to provide notifications (and/or warnings/alerts, video, pictures, photographs, images, advertisements, logos, and/or other output) 700 to a user by use of, for example, an output stage 701. The output stage 701 may be, for example, a display screen 705 to display an alert message, to show a picture, photograph, image, advertisement, video, logo (e.g., the HP logo), and/or to indicate other output 700. Alternatively or additionally, the output stage 701 may also include, for example, a light emitting element (e.g., LED) 710 that turns on to alert the user. In addition or alternatively, the notification 700 may be a sound or audio signal that is emitted from a sound emitting element 715 which may be, for example, a speaker. The sound emitting element 715 may be part of or may form the output stage 701. Alternatively or in addition, the output stage 701 may include a motion-actuating element 719 that triggers motions such as vibrations, movements of movable parts of the variable-function device 110, and/or other types of motions/movements as an output 700. Other types of output generating elements or methods may be used by the output stage 701. An output interface 725 may process the output 700 before being shown via the output stage 701. In one embodiment, a content, image, or program 720 being shown in the computer screen 130 is not interrupted or disturbed by a notification or alert message that current devices show on the screen 130. An embodiment of the invention will show or otherwise indicate this notification or alert message as output 700 via output stage 701.

[0071] As another example as shown in FIG. 8, if an e-mail or instant message 800 is received by the computer 105, then the processor 125 will forward the e-mail or instant message 800 and an e-mail or instant message arrival notification 801 to the variable-function device 110 via communication link 115. An e-mail or instant message arrival notification 801 can be output by output stage 805 of output-function module 600 b. As similarly described above, the output stage 805 may include, for example, a screen for displaying the notification 801 and/or the e-mail or instant message 800, a light emitting element for indicating a message arrival 801, a speaker or other sound-emitting element for indicating a message arrival 801, a motion actuation element for indicating a message arrival 801, and/or other types of elements capable of indicating a message arrival 801. In one embodiment, the module 600 b may include a text-to-speech module 807 for converting the text of the e-mail message or instant message into speech sounds.

[0072] In embodiments where the variable-function device 110 can receive input commands from a user, the user may provide an input 810 to the variable notification device 110 to permit the text and/or attachment(s) of the e-mail message to be displayed (or converted into speech sounds in one embodiment). In one embodiment, the module 600 b may include an e-mail engine (and/or e-mail client) 815 (and/or an instant messaging engine) to permit processing of the e-mail or instant message. The module 600 b may also include a processor to permit the processing and display of the text and/or attachment(s) of the e-mail message.

[0073] As another example as shown in FIG. 9, the variable-function device 110 may include an output-function module 600 c that includes a display screen 900 (or/and other types of displays 905 such as, for example, an LED array). The screen 900 or display 905 may, for example, entertainment-related information 910 such as the name of a compact disc or movie that is being processed by the computer 105 and/or the like. Alternatively or additionally, in one embodiment the display 900 includes a speaker for indicating the entertainment-related information 901 in speech form. Thus, an embodiment of the invention provides a variable number of types of information or content that can be output by variable-function device 110.

[0074] As another example as shown in FIG. 10, an output-function module 600 d may include a transmitter (or transceiver) 1000 that can transmit a wireless output signal(s) 1005 to a device 1010 such as remote control device, speaker, network node, a camera monitor, another computer, and/or other types of devices. An input signal 1005 a from the computer 105 is received via communication link 115 and processed by the I/O interface 135. Based on the input signal 1005 a, the transmitter (or transceiver) 1000 generates an output 1005 to a device 1010. Of course, the output 1005 may be generated in response to other signals that are received by the variable-function device 110, where the other signals may be generated by other devices that can communicate with the variable-function device 110.

[0075] The device 1010 may include, for example, an output interface 1015 and a destination stage 1021 for receiving the output 1005 of the variable-function device 110 and generating an event (or permitting a function) in response to the output 1005. For example, the destination stage 1021 may generate via output stage 1023 an output such as alerts, notifications, texts, images, audio or video output, LED or light emissions, motion outputs, and/or other types of output. The interface 1015 may include, for example, a receiver (or transceiver) 1020 for receiving wireless signals, a signal interface 1025 (for receiving signals in implementations with the optional wired or bus link 1027), and/or other suitable components to permit the reception of the output 1005.

[0076] The output signal 1005 may be, for example, infrared signals, RF signals, or other wireless commands or signals. The transmitter (transceiver) 1000 may also be configured to transmit other frequencies of the electromagnetic spectrum such as, for example, Ultrahigh Frequency (UHF), Very High Frequency (VHF), microwave, or other frequencies. The output signals 1005 may also be wire-transmitted signals if an optional wired or bus link 1027 is implemented between the variable-function device 110 and the device 1010.

[0077] In another embodiment as shown in FIG. 11, the variable-function device 110 may be configured with multiple output-function modules. For example, the variable-function device 110 may be configured with multiple output-function modules 600 e and 600 f to permit the variable-function device 110 to transmit, for example, both a displayed output 1100 to a user and wireless output commands 1105 to a device (e.g., device 1010 in FIG. 10). The number of output-function modules 600 in the variable-function device 110 may vary.

[0078] Other types of output-function modules 600 that can be supported in the variable-function device may include, but not limited to, for example, an I/R blaster, speaker, status display (e.g., in liquid crystal display (LCD) or vacuum florescent), USB hub or other bus hubs, an Ethernet or LAN connection, light-emitting elements, sound-emitting stages, other notification or alert devices, a motion-enabling stage for causing a vibration or other motions to alert a user, a clock, an alarm clock, a display for showing pictures, and/or other types of modules that permit particular functions. The different types of output-function modules 600 may be included or integrated in the variable-function device 110 to permit a variable number of output-related functions to be supported by the variable-function device 110.

[0093] Other types of function modules that can be supported in an embodiment of the variable-function device 110 may include, but not limited to, for example, media transport control buttons, a USB hub or other bus hubs, a removable storage device, an Ethernet or LAN connection, and/or other types of elements or features that permit particular functions.

[0094]FIG. 13 is a block diagram of a variable-function device 110 in accordance with another embodiment of the invention. The variable function device 110 is configured to transmit signals 1305 to the computer 105. In addition or alternatively, the variable-function device 110 is configured to transmit the signals 1305 to a receiving device 1310 to permit particular functions to be performed by the device 1310 (e.g., an upstream device). For example, in response to a manual or wireless input 1315 to the variable-input device 110, the variable-function device 110 may transmit a wireless signal (e.g., an infrared command signal) 1305 to the device 1310 so that the device 1310 can perform a particular operation and/or an event is triggered in the device 1310. The signal 1305 may also be transmitted to the device 1310 via an optional wired link 1320. For example, the device 1310 may be a television or stereo that turns on in response to a particular infrared command signal 1305. As another example, the device 1310 may be a home automation server that permits particular home automation functions to be performed in response to the signal 1305. As noted above, the variable-function device 110 can also receive input signals 1307 from the device 1310 to, for example, trigger an event and/or operation by the module 1325 in the variable-function device 110.

[0095]FIG. 14 is a block diagram of a variable-function device 110 in accordance with another embodiment of the invention. The variable function device 110 may include a module 1400 for alerting or triggering the computer 105 to perform particular functions at, for example, a scheduled time. In one embodiment, the module 1400 includes a clock 1405 to permit the module 1400 to generate an event triggering signal 1410 to turn on the computer 105 and permit the computer 105 to perform, for example, a scheduled event. In one particular instance, the computer 105 may be switched from an off-state into an on-state in response to the event triggering signal 1410.

[0096]FIG. 15 is a block diagram of a variable-function device in accordance with another embodiment of the invention. The variable function device 110 may include a module 1500 that includes a processor 1505. This processor 1505, for example, performs processing tasks to enable some input-related tasks (or functions) 1510 and/or output-related tasks (or functions) 1515 and/or functions 1517 related to a device (e.g., computer 105) that can communicate with the variable-function device 110. Alternatively or additionally, the processor 1505 may perform some processing functions that can be performed by the processor 125 in the computer 105. Thus, the variable-function device 110 permits at least some processing functions to be shifted from the computer 105 to the variable-function device 110.

[0097] The processor 1505 may be embodied as, for example, a micro-controller, microprocessor, digital signal processor (DSP), Application Specific Integrated Circuit (ASIC), programmable logic device (PLD), field programmable gate array (FPGA), or other suitable devices.

[0098] The module 1500 in the variable-function device may also include a memory (storage element) 1520 that can store various software or firmware. For example, the software may be an operating system or an executable program for an application such as electronic mail or web browser. The firmware provides instructions to the processor 1500 for certain functions so that the processor 1500 can launch certain programs or perform other functions independently of the computer 105.

[0099]FIG. 16 is a block diagram of a variable-function device 110 in accordance with another embodiment of the invention. Assume that the screen 130 of the computer 105 is displaying content 1600 that the user does not want to be interrupted. For example, the content 1600 may be a movie or an output of a program being executed by the computer processor 125. A device driver 1605 and filter software 1610 may be programmed to detect for particular events so that when these particular events 1615 occur, then a content 1620 related to these events (event-related content 1620) is instead transmitted by the device driver 1605 via communication network 115 and generated by an output stage 1625 of a module 1630 of the variable-function device 110. Depending on the elements that form the output stage 1625 (e.g., display screen, speakers, light-emitting elements, and/or the like), the content 1620 may be made observable to the user as, for example, an image, video, text, audio sound, motion, light emission, and/or other types of output. Therefore, an embodiment of the invention prevents the interruption of content 1600 that is being shown in the computer screen 130.

[0100] The event 1615 may be, for example, a notification indicating the arrival of electronic mail or instant message, low-battery power alert, and/or other events that may be detected for by the device driver 1605 and filter software 1610. The filter software 1610 performs a comparison between preset data (that represent particular events) and the event signal 1615 to determine if content representing the event 1615 should be displayed in the variable-function device 110.

[0101] Various known methods may be used to permit the output stage 1625 of the module 1630 to generate the event-related content 1620. For example, the filter software 1620 may be code that is in between a driver for the display screen 130 and the application(s) 1650 that sends content to the screen 130. The filter software 1610 may, for example, allow a user to designate the application content that should be generated via the output stage 1625 of the module 1630 in the variable function device 110, instead of generating the application content via the computer screen 130. Thus, the filter software 1610 may allow a user to customize the content shown via the output stage 1625 of the module 1630. Alternatively, the filter software 1610 may have default settings that will cause a particular application content to be generated via the output stage 1625 of the module 1630. Alternatively, the filter software 1610 may allow a particular application content to be generated via the computer screen 130 and the output stage 1625.

[0102] Alternatively or additionally, a plug-in 1655 may be used at the application level to allow an application content to be generated via the output stage 1625 of the module 1630 instead of the computer screen 130. The plug-in 1655 may also allow an application content to be generated via the output stage 1625 and the computer screen 130.

[0103] Alternatively, as part of a software 1670 in the module 1630 in the variable-function device 110, an application program interface (API) can permit application vendors to program an application content to by-pass the computer screen 130, so that the application content is generated via the output stage 1625 of the module 1630. In this particular implementation, the filtering software 1610 may be omitted when generating application content via the output stage 1625 of the module 1630.

[0104]FIG. 17 is a flow diagram of a method 1700 for generating an event-event related content by use of a variable-function device, in accordance with an embodiment of the invention. The method 1700 may run continuously or at representative intervals. Monitoring (1705) for an event is first performed. Upon detection (1710) of an event, a determination is made (1715) if a content related to the event (event-related content) should be generated via an output stage of the variable-function device. If so, the event-related content is generated (1720) via the output stage. The event-related content may be output as, for example, an image, a notification, an audio sound, and/or another type of output. Otherwise, in step (1715), the event-related content is generated (1725) via an output stage of the main device (e.g., a screen of a computer).

[0105] In another embodiment, if a determination is made (1715) that the event-related content should be generated via the output stage of the variable-function device, then the event-related content may be generated via the output stage of the variable-function device and via the output stage of the main device (e.g., the screen of the computer).

[0106] In another embodiment as shown in FIG. 18, the computer 105 and variable-function device 110 may be connected to a network 1800 and may use the Universal Plug and Play (UPnP) standard. UPnP is a standard that uses Internet and Web protocols to enable devices such as PCs, peripherals, intelligent appliances, and wireless devices to be plugged into a network and automatically know about each other. With UPnP, when a user plugs a device into the network, the device will configure itself, acquire an Internet Protocol (IP) address, and use a discovery protocol based on the Internet's Hypertext Transfer Protocol (HTTP) to announce its presence on the network to other devices. Thus, an event occurrence can be handled by the eventing mechanism of UPnP. The device driver 1605 and filtering software 1610 can then determine if the announced event requires filtering. If so, then the event-related content is transmitted via network 1800 to the variable-function device 110 to permit the generation of an output 1805 (e.g., display image and/or audio alert) via output stage 1810 of the module 1815. The output 1805 may be the event-related content or information indicating a state change of a device connected to the network 1800.

[0107] As noted above, a first phase in the UPnP standard is the addressing phase, where, typically, a device that is added to the network 1800 will try to locate a Dynamic Host Configuration Protocol (DHCP) server on the network 1800 in order to acquire an IP address. After the addressing phase, a discovery phase occurs where the added device will broadcast its existence to the network 1800 by use of, for example, a multi-cast version of the Hypertext Transfer Protocol (HTTP) and attempt to obtain information about other devices in the network 1800. In FIG. 18, during a discovery phase, the variable-function device 100 sends a broadcast 1820, while the computer 105 sends a broadcast 1825.

[0108] After the discovery phase, a description phase occurs where a device in the network 1800 can learn about other devices based upon the descriptions of the devices. A description typically includes a state vector that describes the state of the device. In FIG. 18, the variable-function device 110 sends a request 1830 to the computer 105 for a device description, and, in response to the request, the computer sends the device description 1835 to the variable-function device 110. The device description 1835 includes information about the computer 105 and state information 1842 with a state vector 1845 describing the state of the computer 105. The variable-function device 110 can send a signal 1840 to subscribe to events that change a state of the computer 105, and this subscription is indicated in the representation 1850 which identifies all subscribing devices. The state information 1842 may be stored in, for example, an internal or external memory of the computer 105 or in other suitable locations such as a website.

[0109] It is further noted that the device description 1835 of the computer 105 may include hooks for controlling the computer 105. The device description 1835 permits the computer 105 to inform the variable-function device 110 on how the variable-function device 110 can control the computer 105. A standard mechanism to permit control of devices is the Simple Object Access Protocol (SOAP). In FIG. 18, the variable-function device 110 can send SOAP signals to effect changes in the computer 105. As an example, the device description 1835 may provide a Uniform Resource Locator (URL) that provides a description for controlling the computer 105.

[0110] When the state of the computer 105 changes, the state information 1842 changes to state information 1843, with changes occurring in the state vector 1845. The subscribed devices (including variable-function device 110) are then notified via notification 1855 from the computer 105 of the state change in the computer 105. Content that is associated with the state change can be generated as an output 1805 by the output stage 1810 of the module 1815.

[0111] The variable-function device 110 may subscribe to other events (or state changes) that occur in another device in the network 1800. For example, the variable-function device 110 may subscribe to events in a peripheral device 1860 (e.g., a printer). If there is a state change in the peripheral device 1860 (e.g., a printer paper jam), then the peripheral device 1860 transmits a notification 1865 to the variable-function device 110. Based on this notification 1865, the output stage 1810 of the module 1815 can generate an output 1805 related to the notification 1865. Thus, the variable-function device 110 can mimic notifications generated by another device, if the variable-function device 110 subscribes to the other device. For example, if a printer paper jam condition occurs in the peripheral device 1860, then the message “printer paper jam” can be generated by the output stage 1810 of the module 1815. It is further noted that the module 1815 can control any suitable device (e.g., peripheral device 1860, computer 105, etc.) by use of the UPnP standard.

[0112] Referring now to FIG. 19 there is seen a function-producing device, generally illustrated as 104 for exemplary purposes. While the function-producing device 104 will be illustrated herein as the computer 105, it is to be understood that such illustration is not to limit embodiments of the present invention, and that the function-producing device 104 may be any device or assembly that is capable of producing a function for purposes of the present invention.

[0113] The computer 105 is preferably coupled to the variable-function device 110 via the communication path 115. The computer 105 may include an output stage 1625, and the variable-function device 110 for this embodiment of the invention includes a control board 1910 supporting a USB hub 1912 which is coupled to a USB header 1914. A communication link 1920 (e.g. a USB) couples the USB hub 1912 to a processor 1930 which may be operatively connected to at least one module 140 (e.g. an LCD module). As best shown in FIG. 19, the processor 1930 preferably includes or has access to suitable memory 1940 (e.g. flash memory 1940 a, SRAM memory 1940 b, etc.), and an input stage 1960 for receiving a suitable input (e.g. input 145) for being controlled. Input stage 1960 may comprise a plurality of buttons 1960 a for manual manipulation to receive appropriate input signals for control purposes.

[0114] Audio control device 1980 (e.g. a volume knob) may be coupled to processor 1930 for controlling the audio of any device coupled to the variable control device 110 (e.g. a downstream device) or any device (e.g. an upstream device or system, such as a TV or Internet, etc.) coupled to the computer 105. Also coupled to the processor 1930 may be a device 1990 for signaling the processor 1930 at regular intervals in order that the processor 1930 (or any upstream or downstream device) may keep up with some external event. Device 1990 may be a time-of-day clock (e.g. a real time clock). As further best shown in FIG. 19, the variable control device 110 may communicate with any suitable power source 1994 (e.g. AC or a battery) for receiving operative power and with any suitable device 1998 (e.g. a recorder, an encoder, etc.) which is to be controlled by the variable control device 110.

[0115] Referring now to FIG. 20 there is seen the computer 105 communicating with a source of power, generally illustrated as 2000. Operative power passes from the source of power 2000 through a power link 2002 to a power relay stage 2006 which is coupled communicatively to the I/O interface 120 (e.g. USB) and to a stand-by stored power source 2008 for supplying operative power to the computer 105 in the event of a disruption of power from the power source 2000. A power on/off switch 2012 is in power communication with the power source 2000 via I/O interface 120 and power relay stage 2006. Alternatively, the power on/off switch 2012 is in power communication with the stand-by storage power 2008 via I/O interface 120 in the event that there is a disruption of power from the power source 2000. Thus, even when the power on/off switch 2012 is in the “off” position, operative power is being communicated to the variable control device 110 through the I/O interface 120 and the communication link 115. When the power on/off switch 2012 is switched to the “on” position, operative power is being passed to both the computer 105 and the variable control device 110. This embodiment of the invention is an energy efficient embodiment that allows the variable function device 110 to receive power without the computer 105 having to receive power.

[0116] Referring now to FIGS. 21 and 22, there is seen the variable control device 110 having a fixed circuitry 1950 to which one or more module(s) 140 may be coupled. By coupling one module 140 to the fixed circuitry 150, the variable function device 110 may produce a desired function. By coupling a second module 140 to the fixed circuitry 1950, the variable function device 110 may produce an additional desired function. If one module 140 is replaced by a second module 140, or with two or more modules 140, a function produced by the variable function device 110 changes. Thus, additional functions may be generated by adding and coupling to the fixed circuitry 1950 more modules 140, and one or more functions produced by the variable function device 110 may be changed by replacing a first module 140 with a second module 140, or with two or more modules 140. As best shown in FIG. 22, one (or more) device(s) 2020 and/or networks 2024 may be operatively engaged to the computer 105. Device 2020, by way of example only, may be an audio and visual producing device, such as a television; and networks 2024 may be the Internet. The computer may store and/or download into memory or storage any desired function or event from the device 2020 (e.g. an entertainment function) or network 2024 prior to recording the same through the assistance of the variable function device 110. It is to be understood that the particular function of the variable function device 110 may be assigned at any suitable time, such at program run time.

[0117] Broadly, one or more of the modules (e.g. module 140) for embodiments of the present invention may be any collection of one or more of circuitry, software, firmware, and hardware (e.g. display mechanisms, components, or any other suitable elements, etc.), all designed to perform a desired operation.
